Feasibility Study on Environmental Adaptability Test Platform of Rescue Drilling Rig

Ergonomic Exposure Assessment on a Drilling Rig

Dependence of Adaptability on Environmental

This paper concerns the relationship between the detectable and useful structure in an environment and the degree to which a population can adapt to that environment. We explore the hypothesis that adaptability will depend unimodally on environmental variety, and we measure this component of environmental structure using the information-theoretic uncertainty (Shannon entropy) of detectable envi...

the relationship between eq, iq and test format: a study on test fairness

the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...

Modeling and Experimental Study on Drilling Rig Anti-jamming Valve with Bp Neural Network

Article history: Received: 17.3.2015. Received in revised form: 22.9.2015. Accepted: 24.9.2015. An effective anti-jamming system is significant in improving the working reliability of hydraulic drilling rigs. An anti-jamming valve is a core component of an anti-jamming system. A backpropagation (BP) neural network model was established for an anti-jamming valve by analyzing the structure and wo...
